REGENERATIVE GAS-LAWN.

SPECIFICATIONformi'ng part of Letters Patent No. 343,142, dated June J.,1886.

Application filed May 14, 1885.

To all whom if may concern,.-

Bc it known that we, HENRY E. SooToHMER and JOHN YOUNG, citizens of theUnited States, and residents of Chicago, county of Cook, and State ofIllinois,have invented new and useful Improvements in RegenerativeGas-Lamps, of which the following is a specification, reference beinghad to the accompanying draw'- ings, illustrating the invention, inwhich- Figure l is a vertical sectional elevation of a regenerativegas-lamp embodying our invention; Fig. 2, a horizontal plan and sectionon line zr, Fig. 1, showing particularly the reflector-seat andburner-ring and their position relative to the Argand burner; Fig. 3, aperspective of the burner-ring removed from the other parts better to-show its construction.

he purpose of this invention is to provide simpler and more efficientmeans for causing a given quantity of illuminating-gas, consumed by whatis known as the Argand burner,77 to give an increased light. This isdone by an increased or more intense heat, and the object sought is soto utilize air for this purpose by such mechanism as will causel thenearest perfect combustion, and at the same time protect the mechanismfrom destruction by the increased heat.

The principle of admitting, air by various means termed lamps to flamesof gas is known to be old; but the diflieulty of destruc- .tion to themechanism and the clicking up of the parts by carbon has not so far inthe art been sufficiently overcome to insure the public of the practicalutility of such lamps. Te claim to have overcome these objections by thefollowing means:

A represents the ordinary Argand burner with its perforated top part forthe ordinary escape of gas. Centrally through this burner is placed thegas-supply pipe B,which is made to communicate with the interior of theburner A by means of one or more ordinary branch pipes, C, as shown atFig. 1.

Placed around the pipe B where it is subjected to the greatest heat, isa cylindrical sleeve, D, of metal, asbestus, or other heat-resistingmaterial, and placed on the supplypipe B, to come about even with thetop of the burner A, is a cylindrical seat, E,Which serves the doublefunction of reducing the air-space inside of the b'urner A andfurnishing a seat Serial No. 165,515. (No model.)

for the cone F, which is made of some lightcolored heat-resistingmaterial, and somewhat larger than the burner to increase the light andbring the flame into a larger circle before it is drawn into the chimneyG'above.

' We do not claim in this application to be the first to use thedefiecting-cone above the burner, as the Scotchmer and Bent gas-lamp ofChicago and other lamps have a similar (le- Hector, but differentlyarranged and combined-as, for instance, our deliector is combined withan adjustable seat, E, which can be held at different altitudes by meansof a set-screw, a, and which forms the inner wall of the air-passage onthe inside of the burner A, and by raising or lowering it the flame canbe more or less abruptly expanded toward the globe H. A deflector, I, isprovided with a flange, J, at its bottom to rest on the globestand K,and its top part is a truncated cone to form a suitable-sizedair-passage between it and the burner A. It is important that theair-passages which admit air exteriorly and interiorly to the burnershould be about the size shown to supply oxygen to both sides of theflame in such quantities as will be consumed thereby, otherwise thellame will blow or become deadened, according to the amount and force ofsurplus air admitted. To attain this desirable airsupply,care istaken,by means of the flange J on the deilector I, to prevent any airfrom passing up between the deliector I and globe H, and instead thereofto admit a current of air, as stated, to the inside of the burner,thereby supplying both sides of the flame with air and preventing animperfect combustion by the admission of air outside ofthe deliector I,as is the case in the patent to Lipsey, May 29, 1883.

L shows an underllame-protector, which is perforated,and is to admit airin proper quantities to the burner by means of the two passages shownand described. It' desirable always to have it in place, it may behinged to the globe-stand, or it may be held by springclips of ordinaryconstruction to be' readily removable. This is an important constructionin that both air-passages to the burner receive their supply of air froma common source, whereby the supply of air through the passages isequalized, inasmuch as the upwardmoving air in a single column isdivided in icoquantity, according to the amount required in each passageto support combustion.

The metal chimney-top is shown at G, and exteriorly to it is affixed ahousing-support, M, which serves the purpose by extending down into thechimney of forming atight draft-connection. Thechimney-top, byextendingdown into the globe H, causesthe flame from the burner to takean inward direction over the de- {iector F, thereby increasing the heatof the deflector,wherebya nearer perfect combustion is attained and thechimney is made to support the top; but nothing new is claimed for thisconstruction of chimney, but it is employed as best adapted for thislamp.

The globe-stand K is supported by an arm, N, projecting up from acollar, I), which is secured to the lower end of the supply-pipe B bymeans of a bayonet attachment, R, of ordinary construction.

To remove the globe H, detach the globestand K by disengaging thebayonet attachment R. This will allow the globe H and burner-ring I tobe removed downward.

We` claim as our invention and desire to secure by Letters Patentl. Inregenerative gas-lamps, the burner A,

deflector F, globe H, gas-pipe, chimney G, globe-stand K, in combinationwith the protecting perforated plate L, covering the bottom of the lamp,the air-passage between the surrounding plate I and the burner A, andthe passages inside the burner which receive air from a common source,for the purpose specitied.

2. The burner A, globe I-I, gas-pipe, chimney G, globe-stand K,perforated protectingplate L, covering the bottom of the lamp, theair-passage between plate I and burner A, and the passage inside of theburner, which passages receive air from a common source throughprotector L, in combination with the detlector F, and the seat E andpipe B for supporting the deflector and adjusting it to a desiredheight, as and for the purpose specified.
